Environmental Gprs Data Logger The Environmental GPRS Data Logger (EGD) is a wireless device that can measure electromagnetic fields (EMF), including radio frequency radiation (RFR). This data logger has been designed to provide accurate measurements of EMF over a wide range of frequencies.This device uses a low power, high sensitivity receiver and antenna to detect RFR from mobile phones, Wi-Fi networks, microwave ovens, radar systems, etc. The EGD measures the signal level at different distances from the transmitter using a directional antenna. The results are displayed on a LCD screen and stored in memory for later analysis.
